PROCESS OF MAKING HECTOGRAPH COPIES.

SPECIFICATION formingpart of Letters Patent No. 233,684, dated October 26, 1880.

Application filed August 2, 1880. (No model.)

To all whom it may concern:

Be it known that I, GEORGE A. MGIJANE, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Processes of Making Hectograph Copies, of which the tollowing is a specification, reference being had to the accompanying drawings, illustrating the device, in which- Figure l is a perspective representation of a device for carrying out my improvement; Fig. 2, a transverse or cross section thereof.

The object of the present invention is to facilitate printing from what is known as the dry gelatine padsthat is, taking impressions from the hectograph or other gelatine copying-pads and other like devices.

The nature of the invention consists in adapting a roller pivoted to asuitable .handle and having wound around it a roll of paper for the purpose of taking impressions from ahectograph-pad. Thecoilot'paperisbrought, by means of the roller, handle, and hand,onto the copying-pad, and the paper, by the hand and movement of the roller, is moved forward to make the impression as it (the paper) unrolls. The device can also be employed to multiply copies from the electric-pen stencil, papyrograph-steneil, and like devices.

A represents a roller of any desired size or material, wood being preferred. Bis a metal handle of bail form, and at its ends it is pivoted to the roller A, so that the latter may rotate.

It is immaterial how the pivots connectthe handle B with the roller, only so that the roller can be readily detached from the handle when required to supply the roller with paper, or for other purposes.

The gelatine pad D is contained in a case or pan,G,the sides of the pan in this case projecting above the pad.

\ There is wound round the roller A a sheet of paper, E, of any desired length, to take the impressions on, and after the matter to be copied has been transferred to pad D in the ordinary manner the handle B is grasped so as to bring the fingers on its opposite side from the hand 2 and the thumb on the opposite side of the handle from the fingers and down on the paper at x, or such other convenient place on it as will keep the paper from unrolling. The other hand is then made to grasp the end of the sheet of paper, as shown at z. The paper E under the roller is then brought down onto the pad D, at the front thereof, and it is kept in tension by the left hand 2, while the roller A, by the right hand, is moved forward to the opposite margin of the pad, the thumb during the unwinding of the paper being removed from ac. The thumb is again replaced at 00, so as to hold the paper to the roller, and the roller is lifted up and the operation is repeated till the paper has been filled with impressions.

It is proper to state that the front of the pad is at the right hand of the operator, and that the roller, with paper thereon, is to be moved from right to left.

The inking of the pad should notbe done. so closely to the margins O O of the case A as to prevent the paper under the roller from taking a full impressionthat is,in cases where the margins project above the pad, as the one shown in the drawings.

The applicant makes rollers and handles to suit any sized pads, or for the other purposes mentioned.

In hectographin g as at present done the sheets to receive the impressions are brought fiat on the pad, and after the impressions are taken they are peeled off. This is a slow and laborious process, and too expensive.

By the means herein set forth impressions can be taken with great rapidity and the sheet or roll of paper out after the printing is done.

111 some instances it may be necessary to employ two rollers attached to one handle, in which case they may be smaller than where one roller is used, to print closer to the margin of the pan or case of the pad.

I claim and desire to secure by Letters Patent The process of making a series of copies on a continuous sheetfrom ahectograph-pad,which consists in successively passing the roller car rying the paper over thepad, and at the same time drawing (in the manner specified) the printed paper from the top of the roller in the direction in which it moves, substantially as described.

GEORGE A. MGLANE.
